1.3 Operating range and correct usage

The grinding machine BG-250G11/G13 is exclusively

may not be used for other purposes. The

manufacturer will not be liable for damage or injury

resulting from such incorrect usage. In these cases

the user assumes all risks.

Technical Data November 2004

1.5 Advice for operators of the machine

When you use the grinding machine BG-250G11/G13 it is

ossible to exceed the allowed scale of sound level of 85

db(A). That sound level varies depending on the

location. If the scale of sound level reaches 85 db(A) or

more, the operators and the persons who work in the

surroundings must wear noise protection.

Pay attention that you always put down the machine on the kick

stand if not grinding. If you put down the machine on the grinding

disc, the flexible coupling will deform causing unequal wear of the

tools and increased vibration level.
